Abstract

The transfer capability evaluation requires the consideration of various pre- and post-system contingencies to ascertain network security and the reliability of power systems. In this paper, the effects of single line (N-1) outage contingency and simultaneous transfer were considered in Nigerian 330-kV network. The results show that a single line outage not only lowers the available transfer capability (ATC) but can result in an infeasible operating condition (system collapse) of the Nigerian 330-kV power grid. Moreover, an additional source area results in higher transfer capability.
